Is there a man on earth so perfect found, / Who ne’er mistook a word in sense or sound ? / Not blund’ring, but persisting is the fault ; / No mortal sin is lapsus linguae thought : / Clerks may mistake ; considering who ‘tis from, / I pardon little slips in Cler. Dom. Com.

1850, Moses Margoliouth, A pilgrimage to the land of my fathers

... a poor woman who owed one thousand piastres—about £30—rushed and seized hold of the coffin, but instead of saying, "God bless the Bey," she, by an unfortunate lapsus linguæ, exclaimed, "God do not bless the King," which slip is quite natural in the Arabic expression.

“As he said this, you can imagine our surprise; we thought the man must be out of his head, or that it was a lapsus linguae: yet the strength of his convictions caused us to persist in our first opinion. […]”

In Linz, the late principal of the local high school was considered the originator of this lapsus linguae. [discussing the phrase 'Unvorbereitetwieichmichhabe...', a jocular alteration of the phrase 'Unvorbereitet wie ich bin...']

The term is usually spelled Lapsus Linguae with two initial majuscules (Duden), but Lapsus linguae (Brockhaus and Meyer)[2] is also common, and the Latin and English spelling lapsus linguae is common in specialist literature. — German orthography calls for all nouns to begin with majuscule letters, but this and other foreign phrases are often left entirely in minuscule. (Latin terms are never written entirely in majuscule as in classical, but not later, Latin.)

Condensation, a mechanism evident in dreams, neologisms, lapsus linguae and jokes, consists of the joining of components of different physical representations in a single element (word, image, representation), which are found to be connected associatively. For example, in a dream can appear a person, with the name of another person or the overcoat of a third.
